App'lieetien filed Aprn is, 1902.

To all whom it may concern: I

Be it known that I, HENRY HALSEY, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in ElectricBatteries, of which the following` is a full, clear, and exactspecification.

This invention relates to batteries, and o especially to that class ofbatteries wherein means are provided for maintaining movement of theelements or the electrolyte.

yThe object of the present invention is to provide a battery of thisclass wherein all I the parts shall be simple and readily fittedtogether and wherein the interior of the battery will be readilyaccessible without necessitating a substantially complete dismantling ofthe battery.

The invention also comprehends .novel means for brushing the elementsand for establishing 4movement of the electrolyte.

The invention will be more fully described with reference to the formthereof shown in the accompanying drawings, in Which-J Figure 1 is a topsectional view of a battery-cell embodyingr my invention, said sec-vvtion being taken upon the line X X of Fig.V 2; and Eig. 2 is a sectionalView of the same.

In the drawings, 1 represents a suitable pedestal upon which thebattery-case is to be mounted. This pedestal. also serves as a bearingfor the shaft 2. Upon the pedestal is fitted the battery-case 3, thecase having a rentrant portion 4, which tits upon the pedestal 1. Thecase may be fitted upon the pedestal in anyv suitable manner.v Aconvenient arrangement, however, is that shown :in the drawings, whereinthe flooring 5, upon 4o lwhich the battery is to be mounted, restsagainst the flange 6 upon the lower end of the pedestal and thebottom ofthe case 3 rests upon the flooring 5. An additional bearing 7 is mountedupon the flooring 5and One of the elei ments 8 of the battery,preferably the zinc, rests upon the bottom of the case, being suitablyarranged to permit free circulation of the electrolyte between theparts. In the Serial No. 103,645. (No model.)

present instance the element S rests upon 5o the legs 9 and theperforations 10 l0 permit Y ree circulation of the electrolyte. VA conlaportion 15 of the shaft 2 is rectangular in 6o cross-section, and thecentral opening of the spider 14 is also rectangular and fits upon theportion 15 of shaft 2. The spider rests against the lugsfl. Theconductor 17 for the external circuit of the battery is connected to theconducting-strip 11, and the conductor 18 is connected to the end of theshaft 2. Upo'n the element 13 are mounted the brushes 19 and 20,composed of any suitable material-such, for example, as hard rubber-eachof which 7o brushes projects outward and upward and l preferably lightlycontacts with the elements 8. The brush may be of any suitable form andmay be mounted upon the element 13 in any suitable manner. In thedrawings the brushes are mounted vertically upon the element; but

in practice in many cases it will be found de- Sirable to mount thebrushes nspirally, the top of the brush beginning near the top of theelement and the brush winding around the 8o element downward toward' thebottom. In the drawings the clamps 2l serve to hold the brushes inposition upon the element. Perforations 22 22 are also provided'in orderthat lthe brushes will present a minimum of resistance to theelectrolyte; but the use of these perforationseand their contour andarea, it' used, will depend upon individuall circumstances.

The gear-Wheel 23, carried by shaft 2, 9o`

meshes with the gear-wheel 24, mounted upon shaft 25. Shaft 25 isdriven-in'this instance' by a belt 2b from the motor 27. Themotorcircuit is as follows: from shaft 2 by wire 28 to the motor; fromthe motor 27, bywire 29, v rheostat 30, rheostat-arm 31, and wire 32 tothe conducting-strip 11.

The cell is assembled by first slipping the casein position upon thepedestal l and placing the element 8 in position. Element 14: is thenslipped over shaft 2 and placed in position upon the rectangular portionl5. The electrolyte having been poured in, the cover 12 is tted on. Tofit the cover in place, the only manipulation necessary is to see thatthe shaft 2 and conducting-strip 11 project through the proper openingsin the cover. The cover having been placed in position, the wires areconnected to the respective contacts. When the battery-circuit isclosed, the motor-circuit will also be lclosed through the rheostat-arm31. The initial output of the battery will always be sufficient to startthe motor, which through shaft 25 and gears 24 and 23 rotates shaft 2,and thus rotates the element 14, causing brushes 19 and 2O to move theelectrolyte around in the angular channel between the elements and alsoto mechanically brush the active surfaces of the elements 8. It is notessential that the brushes shall make contact with the elements 8, forin such case the movement of the electrolyte will be sufiicient toprevent polarization of the battery. As the speed of the motor increasesthe polarization decreases, and hence the output of the battery will bemaintained constant at a constant speed of the motor. The output of thebattery may be varied in the usual manner by resistance in tbe externalcircuit or by varying the speed ofthe motor, and. consequently varyingthe speed at which element 13 rotates.

It will be understood that the invention above described is capable ofvarious modifications, and I therefore desire it to be understood that Ido not limit myself herein to the precise construction shown.

Having thus described my invention,I declare that what I claim as new,and desire to secure by Letters Patent, is

1. In a battery, the combination of a casing having a rentrant portion,a shaft mounted therein, a cylindrical element mounted upon said shaft,a similarly-formed element supported in the casing, opposite. saidfirstnamed element, an electrolyte between the same, and means forrotating the shaft, substantially as described.

2. In a battery, the combination of a pedestal, a shaft having bearingsin said pedestal, a casing adapted to be supported on said ped estal, anelement supported in said casing, an element supported upon said shaft,said elements being cylindrical and concentrically arranged,anelectrolyte surrounding said elements, and means for rotating saidshaft, substantially as described.

3. In a battery, the combination of a pedestal, a shaft having bearingsin said pedestal, a casing adapted to be supported on said pedestal, anelement supported in said casing, an element supported upon said shaft,said elements being cylindrical and concentrically arranged, anelectrolyte surrounding said elements, one of said elements carrying abrush which contacts with the other element, and means for rotating saidshaft, substantially as described.

4. In a battery, the combination with a cell containing an electrolyte,of a stationary element supported in said cell, a vertical shaftentering said receptacle from the bottom thereof, a tubular elementsupported upon said shaft and surrounding the same, and means, outsideof the cell, for rotating said shaft, substantially as described.

5. In a battery, the combination with a cell containing an electrolyte,of a stationary1 element supported in said cell, a vertical shaftentering said receptacle from the bottom thereof, a tubular elementsupported upon said shaft and surrounding the same, a brush or brushesmounted on said tubular element, and means, outside of the cell, forrotating said shaft, substantially as described.

6. In a battery, the combination of a vertical shaft, means forimparting motion to the same, a bearing for said shaft, a cell supportedupon said bearing, an electrolyte in said cell, and elements in saidelectrolyte, one of said elements being mounted upon said shaft,substantially as described.

7. In a battery, the combination of a cell containing an electrolyte,and two cylindrical elements, one of which surrounds the other, meansfor imparting movement to one of said elements, and a brush or brushescarried by said movable element, substantially as described.

8. In a battery, the combination of a rotatable shaft, a bearingtherefor, a cell adapted to be supported upon said bearing and having arentrant portion, and an electrolyte and battery elements in said cell,one of said elements being supported upon said shaft, substantially asdescribed.

In testimony whereof I aix my signature in presence of two witnesses.
